Every restaurant has them.
Rose is an 81 year old Jewish woman who comes in to eat minestrone soup at Bloggiano's about three times a week. I know she's 81 because she pulled me over on my first day of training to say, "You're new" on my first day of training and told me her life story.
I've been informed by some of the other employees on how to deal with Rose.
1) Never joke with her when she doesn't know your name, no matter how many times she's met you. Her response: "I'm 81. I'm not supposed to remember. You're supposed to remember." (I hope you're doing a Jewish New Yorker voice in your head, because that's how she sounds.)
2) Never respond with, "We don't serve minestrone soup anymore" when she orders it. We keep some frozen for the people like her who still come in to get it after it was removed from the menu.
3) Never walk by her table without smiling, or stand around doing nothing where she can see you. She'll claim she's the boss and send you home.
4) If she asks you to sit with her, DO IT. But if you get stuck there, just pull another server into the conversation and sneak away.
In my first experience with Rose, she told me how old her children were and then said she has a granddaughter who has, "a better job than any of you!" Thanks Lady.
While some servers try to avoid her all together, I took another route. I told her I am Jewish and that I lived in Israel last year. Now she loves me.
I choose to be on her good side, just in case.
